We use Spotify family (6 members) across several devices. I've been playing with Spotify in the car trying to understand why it's felt so unstable and I think may have found the answer. I believe that most of the problems I've been experiencing are because Tesla didn't implement Spotify device hand-off properly.
The most common problem I see is an infinite loading screen:

It seemed to randomly happen in the Playlist screen as wall as the Song screen. I say seemingly random because I found the pattern. Turns out the Tesla only gets stuck when I've been running Spotify on my Android phone. If I completely close the Spotify app on my phone, the loading issues go away.
The next issue is with sending music from the phone to the car as the playback device. Even though the song plays, sometimes it doesn't show that there's even a next track. The phone sees it, but the car does not.

Finally, I've had times when even though I select the car as the active playback device:

the car does a little refresh spin and then tells me music is still playing on another device.

IMO, device hand-off is not implemented correctly. The car is not
taking active status away from another device when the user performs an action that should make it active (for example, browsing or selecting a track which leads to the infinite loading issue.) The car is also not
receiving active status when another device tries to push active to it (switching device to the car from the phone).
I'd like to know if anyone else can confirm these things. And if so, maybe we can open up some bug reports.
